WATCH.

Specification of Letters Patent.

Patented Sept. 1'7, 1907.

Application led June 1,1907, Serial No. 376,795.

To all whom it may concern:

Be it known that I, ADoLrn GnnsoN, a subject of the Emperor of Germany, resid'ng at New York city, Manhattan borough, county and State of New York, have invented certain new and useful Improvements in 7Watches, of which the following is a clear, full, and exact description.

This invention relates to watches, the object being to produce a watch case that can be cheaply manufactured, special means being provided for removably holding the watch mechanism within the outer easing by means ol' the stem. My improved watch case is particularly adapted for cheap grades ol watches, being so constructed and assembled as to provide dustprool' covering for the mechanism, without the necessity of any exact fittings.

My invention comprises the novel features of improvement and combination and arrangement of parts, which I will now proceed to describe and finally claim, reference being had to the accompanying drawing, which forms part of this specification, wherein- Figure l illustrates a sectional view ol' the outer member of my improved watch case, the inner container or holder beingI in elevation and partly in section; Fig. 2 is a detail top plan view, partly in section, of the outer member of my improved watch-case; Fig. 3 is a detail view in elevation, of the inner container or holder of my improved watch-case, partly in section, showing a portion of the watch mechanism therein contained; Fig. 4 is an enlarged fragmentary detail view, showing the winding stem which forms the releasable locking device for the inner container or holder ot' the case; and Fig. 5 is a diagrammatic view of the mechanism with which the stem co-acts.

Lilie numerals of reference indicate similar parts in the several views.

Referring to the drawing, l. indicates the outer member, or shell., of my improved watch case, while 2 indicates the inner container or holder lor the watch mechanism, which is diagrammatically indicated by the numeral 3 (Fig. 3). For the sake of clearness, the winding stem side of the shell will be hereinafter termed the front, and the opposite side the back. At the back of the shell l, I place a nib 4 Figs. l and 2) which extends sul lieiently from the shell l to enter an opening 5 in the container 2 when the said holder or container is in position in the shell l, as shown in Fig. l. The nib 4 can be soldered or otherwise secured to the shell l. The front of the shell l is provided with the usual neck G which contains the pendant '7 of the )iariety used in most stein-winding andstem-setting watches. The pendant 7 carries the usual winding and setting stem 8 which, at its inner end, is squared and adapted to enter the rotatable square bored bushing 9 which forms part of the watch mechanism and is not in itself apart of my invention.

To fullil the object of my invention I have modified the stem 8 to the ext-ent of adding a stop l0, the object of which will hereinafter appear. The operation of the stem for winding the main spring and setting the hands of a watch is well known, but a brief description thereof will now be given in order to bring ont one ol' the features of my improvement.

The stem S is longitudinally movable in the pendant 7 and when pushed to its innermost position the squared end ll thereof will be contained within the square bore l2 of the bushing .()to an extent suflicient to cause the clutch 13 to vremain disengaged from the jaws 14 and engage with the jaws vl5 (Fig. 5) whereby the gear lli, which is attached to the jaws l5, is free to revolve with the bushing 9 owing to the square end cylindrical spindle 17, the gear 1G being loose on the spindle 17, andthe square end 1S of spindle l? being slidably fitted to the bore l2 of the bushing 9. When the stem 8 is in their innermost position, and revolved, the gear I6, which meshes with the gear 19, which in turn is geared to the main spring of the mechanism, is caused to wind up the said main spring. Fig. l illustrates the stem in the winding' position. In order to set the hands of the watch, the stem 8 is pulled outwardly until the stop 2O contacts the pendant 7. When in the latter position the spring 2l. will have pushed the spindle 17 and clutch 13 thereon away from the gear 16 and into mesh with the jaws 2l of the gear 22, which by means of the gear 23 operates the handsetting mechanism. The hands of the watch can now be set by rotating the stem S, the spring winding mechanism remaining idle (see dotted lines 24, Fig. 5). The winding and setting mechanism per sc forms no part of my invention and is referred to simply to set forth an operative mechanism. As can be seen in Figs. I and el the holder or container 2 is provided with an opening 25 large enough to allow the square end ll of the stem S to pass therethrough and into the bore l2 of the bushing 9. When the stem S is in either the setting or winding position, the said, square end ll of the stem S will still be within the opening 25,' therefore the holder or container 2 cannot be removed, as it will be held down by the said squared end ll and the nib 4. To prevent the holder or container 2 from rattling, or from being prematurely displaced, I have provided a spring 26 adjacent to the nib 4 (see Fig. 2), retaining brackets 27 being provided to keep the spring from getting out of register with the said nib Ll. The sprinLT 2G acts to force the holder or container 2, when in position, forwardly toward the stem, whereby sufficient friction, between the case l andthe holder or container 2, is caused to prevent the member 2 from being easily displaced. The full lines in Fig 2 indicate the position of the spring 26 when the holder or container is removed, and the dotted lines indicate the position of the spring when the container is in position.

As can be seen by Fig. 4, the outer shell l is provided at the'top thereof with a rounded upwardly extending annular flange 28 which is adapted to snugly fit an annular recess 29 in the .container or holder 2, the said recess being formed between the wall 3() of the said holderl or container 2 and a downwardly extending annular flange 3l carried thereby. The said holder or container 2 is also provided with a bezel 32 which re'- ceives the crystal 33.

lt is obvious from the foregoing description that the holder or container 2 and shell l are held together by means of the winding stem 8, nib 4 and spring 26 together with the opening 5 in the holder or retainer 2 and the bushing 9 of the watch mechanism, while the joint made by the flange 28 and recess 29 renders the case dust-proof. To remove the holder or container 2, it is but necessary to pull out the stem 8 to its full extent whereby the squared end ll thereof will be freed from the bushing 9 and opening 25 in the wall 30 of the holder or container (see Fig. 4). The holder or container 2 can then be lifted at a slight angle until the nib 4 is free from the opening 5, and the holder or container can then be removed for the purpose of cleaning or fixing the mechanism. The function of the extra stop l0 is for the purpose of causing the stem 8 to perform a triple function, Ordinarily there is one stop 20 and a collar or final stop 34, the stop 2()A usually being normally against the end of the pendant 7, for the winding position, and the final stop 34 for the setting position, the stop 20 being in this latter instance pulled into the pendant 7. In my arrangement the final stop 34 does not come in contact with the pendant 7, until it is desired to take the holder or container 2 out. The stem 8 therefore is adapted for a triple purpose, viz't for wind'- ing the main spring, for setting the hands when pulled out to the extent of one stop on the stem, and for releasing the holder or container when pulled out the full extent.

Having now described my invention, what I claim and desire to secure by Letters Patent is:

1. A watch comprising an outer shell, an upwardly extendingl annular ange carried by said shell, a removable holder for the watch movement within said shell, said holder' being provided with an annular grooved portion adapted to fit the annular flange on said outer shell, said annular grooved portion being provided with a bezel for the crystal.

2. A watch comprising an outer shell, an upwardly extending annular flange carried by said shell, a removable holder forv the Watch movement within said shell, said holder being provided with an annular grooved portion adapted to fit the annular ange on said outer shell, said annular grooved portion being provided with a bezel for the crystal, and means, controlled by the winding stem for sai'd movement, adapted to releasably hold said holder in position.

3. A watch comprising an outer' shell, an upwardly ex tending; annular flange carried by said shell, a removable holder' ior the watch movement Within said shell, said holder being provided with an annular grooved portion adapted to fit the annular flange on said outer' shell, said annular grooved portion being provided with a bezel for the crystal, a removable container within said shell adapted to hold the movement, and means, controlled by the winding, stem for said movement, adapted to releasably hold said container in position.
